+Subject: [PATCH] Remove error counting in OpenMP parallelize_gemm
+
+This resolves a compilation error associated with
+Eigen::eigen_assert_exception. It also eliminates the counting of
+exceptions that may occur in the OpenMP parallel section. If an
+unhandled exception occurs in this section, the behavior is non-conforming
+according to the OpenMP specification.

+Subject: [PATCH] Fix multi.dot Graphviz regression test
+
+Commit d6602ad of 2018-12-01 fixed the regression test broken by commit
+2d55978 of 2016-07-01. This revealed that `test/graphs/multi.dot` was
+failing.
+
+`multi.dot` was introduced in commit 2b3f088 of 2010-11-07 together
+with many of the other tests still here today. It has not been touched
+since. It is a DOT-file containing two digraphs. The regression test
+compares the JPEG images rendered from the DOT-file by pydot with those
+rendered by Graphviz's dot directly.
+
+Commit 66734d2 of 2016-07-01 is the actual cause of the failure. It
+changed one of the render methods of the regression test,
+`_render_with_pydot`, from calculating a single hash for all the JPEG
+images to calculating separate hashes for each JPEG image and then
+concatenating those hashes in one long string. The other render method,
+`_render_with_graphviz`, still calculates a single hash over all data.
+For DOT-files that generate only one image the end result is the same,
+but because `multi.dot` has two graphs, it produces two images and this
+leads to comparing a string of two hashes with one single hash.
+
+I do not think the change in generating the hash was intentional, for
+the following reasons:
+- Commit 66734d2 states that its purpose was to adapt the test to an
+  API change in pydot. It does not mention a deliberate choice to
+  change the testing method.
+- There was no effort to change `_render_with_graphviz` to also produce
+  multiple hashes.
+- Except for easier debugging in case of a failing test with multiple
+  images (AFAICT, only `multi.dot`), I do not see much added benefit in
+  checking a concatenation of the hashes of all images vs. checking one
+  hash of all images together: In both cases the test will fail if one
+  or more images is rendered differently.
+- Given that there were many commits authored that same hour, including
+  commit 2d55978 which broke the regression tests, I suspect the author
+  did not run the tests for each individual commit, but only at the end
+  of that batch, and was therefore also not alerted of this change by
+  the test suite.
+
+Assuming that the change was not intended, this commit will now revert
+`_render_with_pydot` to the old behavior of calculating a single hash
+from all JPEG image data.
+
+Tested with Debian 9.9, Graphviz 2.38.0-17, Python 2.7.13-2 and 3.5.3-1.
+
+Fixes https://github.com/pydot/pydot/issues/204.
